Robot‐Assisted Measurement of the Critical Micelle Concentration

Advanced Intelligent Systems
The critical micelle concentration (CMC) is the key characterization of surfactants. To date, no method can yield sequential CMC measurements in an automated fashion.

Dielectric Relaxation of Ion-pairs, Micelles and Hydration in Aqueous Hexyltrimethylammonium Bromide Solutions

Chemical Thermodynamics and Thermal Analysis, 2022
Through dielectric measurements of aqueous n-hexyltrimethylammonium bromide solutions, the structure and dynamics of ion-pairs, micelles, and water are investigated as functions of concentration and temperature. The frequency range of the study was ∼ 0.2

Exploring drug-surfactant interactions and their impact on the intrinsic surface properties of aqueous dissolution media

British Journal of Pharmacy, 2022
Surfactants are often used to improve the solubility of a compound for dissolution studies in aqueous media. Having observed non-linear solubility enhancement with increasing surfactant concentration, this study investigated the effect of a poorly ...

Critical micelle concentrations of lipoteichoic acids [PDF]

Journal of Bacteriology, 1986
Purified lipoteichoic acids (LTAs) from several gram-positive organisms have been shown, by methods involving spectral changes of an added merocyanine dye probe, to have critical micelle concentrations in the range of 1 to 10 micrograms/ml, suggesting that acylated LTAs in their monomer forms may represent the major configuration of extracellular LTAs ...

Accurate and sensitive probing of onset of micellization based on absolute aggregation‐caused quenching effect

Aggregate, 2022
Probing the onset of micellization, or determining the critical micelle concentration (CMC), is of crucial importance while remains to be challenged by growing demand for extraordinary sensitivity and accuracy.

Determination of critical micelle concentration of cetyltrimethylammonium bromide in presence and absence of KCl and NaCl in aqueous media at room temperature by viscosity measurement

Bibechana, 2014
NOTE: The correct reference list was added to this article on 08/07/2014. Viscosity measurement of cetyltrimethylammonium bromide in presence and in absence of KCl and NaCl in aqueous media is done. The results showed a sharp increase in viscosity with

A Surfactant Concentration Model for the Systematic Determination of the Critical Micellar Concentration and the Transition Width

Molecules, 2021
The critical micellar concentration (cmc) is a fundamental property of surfactant solutions. Many proposed methods for the definition and determination of the cmc from property-concentration plots yield values, which depend on the studied property, on ...
